Abstract
Die Erfindung bezieht sich auf einen gedämpften Tilger zur Reduzierung von Schwingungen eines Hauptsystems 10 mit rotierendem Maschinenteil. Eine besondere Ausbildung besteht darin, dass an oder in dem Hauptsystem 10 mindestens ein Zusatzschwinger angebracht ist (Fig. 1).The invention relates to a damped absorber for reducing vibrations of a main system 10 with a rotating machine part. A special embodiment consists in that at least one additional oscillator is attached to or in the main system 10 (FIG. 1).
Description
Die vorliegende Erfindung betrifft einen Tilger zur Reduzierung der Schwingungen eines rotierenden Maschinenteils. Wellen, Walzen oder Dorne werden heutzutage aus Kostengründen meistens hohl gefertigt. Somit liegen die Biegeeigenfrequenzen dieser Maschinenteile in tieferen Frequenzbereichen 5 bis 150 Hz. Da die genannten Teile sehr geringe Materialdämpfung haben und deren Biegeeigenfrequenzen durch den eigenen Betrieb der Maschinen oder aber auch durch die von außen auf die Maschine übertragenen Schwingungen angeregt werden, entstehen resonanzartige Schwingungen an diesen Maschinenteilen. Die Schwingungen beeinflussen die Funktionalität, Produktivität, Qualität und Genauigkeit der betroffenen Maschinen, wie Textilmaschinen, Druckmaschinen, Zeitungsmaschinen etc. negativ.The The present invention relates to a absorber for reducing the Vibrations of a rotating machine part. Waves, rolls or Mandrels are now made mostly hollow for cost reasons. Thus, the bending natural frequencies of these machine parts are in deeper Frequency ranges 5 to 150 Hz. Because the parts mentioned very low material damping have and their Biegeeigenfrequenzen by the own operation of Machines or even by the transmitted from the outside to the machine Vibrations are excited, resonant vibrations occur on these machine parts. The vibrations affect functionality, productivity, quality and accuracy affected machines, such as textile machinery, printing machines, Newspaper machines etc. negative.
Zur Tilgung der resonanzartigen Schwingungen eines drehenden Teils der Maschine, das in folgenden Abschnitten als Hauptsystem genant wird, werden Zusatzschwinger an oder in dieses Hauptsystem angebracht. Die Parameter dieses Zusatzschwingers (Masse, Steifigkeit und Dämpfungskoeffizienten) können so optimiert werden, dass die Schwingungen des Hauptsystems möglichst klein werden.to Repayment of the resonance-like vibrations of a rotating part of the Machine, which will be referred to as the main system in the following sections Additional oscillator attached to or in this main system. The parameters this additional oscillator (mass, stiffness and damping coefficients) can be optimized so that the vibrations of the main system as possible become small.
